The invention Aprimarily has for its object to provide a simple, compact, and economically manufactured combined water circulating pump and throttle control for model T 1' Ford motors mountable as a simplev attachment and without modification or addition of special parts over those comprising the standardmotor equipment.

In its more detailed nature theinvention resides in the provision of a simple attachment of the character stated comprising a bracket, bearing hangers projecting from the bracket, one being hollow to communicate with the block inlet of the water jacketing, said bracket being mountable by use of the usual screws that hold the water flow head `against the said engine block inlet, bearings carried by the hangers, a pumpv housing carried bythe hollow standard, a shaft rotatable inthe bearings, a pulley on one shaft end adapted to be rotated by engagement with the engine lfan belt, a pump impeller on the other shaft end and in the housing, a governor device on the shaft, and crank and arm devices carried by the bracket and connected with the carbureter throttle valve and adapted to be actuated by the governor controlled by the speed of the enginev to actuate the throttle valve. y

With the above and other objects in view that will hereinafter appear, the rinvention further resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully described,

then be particularly pointed out in the appended claim, reference beingl had to the accompanying drawings, in which Figure 1 is a side elevation illustrating the application of the invention. y

Figure 2 is a central longitudinal section of the device taken horizontally.

Figure 3 is an end view of the device looking at the pump impeller, the housing cap being removed.

In the drawings in which like numerals of y reference indicate like parts in all of the figures, lcgenerally designates the internal combustion engine upon-which the invention is mounted as an attachment, 2 the usual water jacketing equipment thereof, and 8 the radiator which, together with the water jacketing and the flow and return connections 4 and 5, forml the usual thermo-Siphon cooling system. V

The usual fan is indicated at 6 and the same is driven in the usual manner by the fan belt 7. v d

In the illustration a Ford model T motor is illustrated and as the cylinders of this type of motor are .cast-in spaced pairs, 8 indicates the space between the cylinder pairs which serves a function later yto be described. The carbureter is indicated atQand` 10 indicates the usual throttle control lever or crank.

It is to .be understood that our inventionis in the nature of an attachment Vwhich may be readily and conveniently attached to the ,engine without reconstruction or change of to remove the usual waterv intake head which is secured to theY motor side by the usual machine screws 11 and mount ourV attachmentas a substitute for that head, using the same screws. i I

In the foregoing description all ofthe elements referred to are common equipment and .perse form no part of our invention.

In the practical development of our invention we provide a mounting bracket 12 having holes`13 to 4receive the securing screws 11 by which the bracket mayv be screwed upon the motor as above described.

` A pair of bearings 14 fre provided andare spaced from and carried upon the bracket by the bearing standards 15 and 16,- the latter being hollow as alt'17 'to Communicate with the' water jacketing: of the motor. Y

The* hollow standard 16 is enlarged as at 18 to Vform a housing for the pump impeller 19 having curved impeller blades and being mounted on one end of a shaft 20 which is rommel@ in the bearings 14.

Upon the other end of the shaft 20 and in position for beingengaged by the fan belt 7, is mounted a pulley 2l andby this means rotation is imparted to the shaft and the impeller mounted thereon. y

A governor is mounted upon the shaft between the bearings 14; and includes a fixed block 22 pin secured to the shaft and a slide block 23, the said blocks being link connected and suitably weighted as Vat 24 in the usual manner. The usual slide blockreturn and resistance springis alsoxprovided and is indicated at 25.

At the juncture of the standardl and the main bracket portion 12 the bracket isoprovided with a bearing 26 to rockably receive fthe shaft 27 uponone end of which is secured acrank arm28. VIt willjbe observed by reference to Figures land 2 ofthe drawings that the crank Yarm is of a length for extending back to a point beside the motor block space 7 for a purpose later to be described, and a coil Y spring' 29 is coiled about the bearing end and has one end thereof in engagement with the bracket and the other end thereof in engagement with the arm to hold' the arm to a normalpposition also hereinafter described in detail'.

Upon the other*` end of the shaft 27 is `mounted-abifurcated arm- 30 connected as at 31 witha sleeve 32 slidable on the shaft 20 and normally held against the slide block 23 by the said coil spring 2,9. 1 Y

Inpractice the free end of the arm 28 is link-connected as atV 33jto the throttle valve c'ontrolling'crank 10 so that when the arm 28 is rocked it will impart its movement to the said crank l0V and effect adjustment of the throttle valve. c e

In operation, the shaft 20 being rotated by the pulley and beltconnections 2l and 7 will cause rotationv of the impeller 19 and cause ""forced circulation of the cooling Water x through the water jacketing, the radiator and kbl the iiow. and return connections 2, 3, 4 and 5 respectively. l

v,The motor is, of course, started in the usual manner by the use of the ignition switch and starting crank, the sleeve 32 and coil spring equipment 29 rendering possible this independent movement` .Whenthe motor is'in f operation the movement of the throttle valve `mounted on the shaft 20. As

to control passage of mixture to theV motor is automatically controlled byl the' governor the shaft rotates the `weights of the 'governor are thrown outwardlyiby V"centrifugal force contracting `motion Y is transmitted `through tthe link `conthe slideblock 23 and causing the bifurcated arm 3 0` to rock andk in turn set up a rocking motionof the Vcrankcarm 28, which rocking l nection 33 tothe throttle valvecrank 10. Y The link- 33passesthrough the motor space 8.

circulating pump and throttle control device mountable as a compact attachment to the conventional form of motor without the necessity of boring special holes or costly substitution of parts and which efciently s upon an internal combustion engine having a e carbureter and a throttle valve to control its output and water jacketing and a fan on a shaft driven from said motor, spaced standards projecting from the bracket and supporting bearings, a pump shaft rotatable in the bearings, a pulley on one end of the pump shaft and adapted to be rotatably associated with the fan shaft of the motor, a pum on the other end of the pump shaft to orce water circulation through the jacketing, a governor von said pump shaft between the bearings comprising a fixed block secured on said pump shaft, a slide block on said pum shaft, weighted links connecting the blocks, a spring tending to separate the blocks, a rocker shaft rockably mounted on said bracket, a rocker arm on one end of said Vrocker shaft and link-connected to the carbureter throttle valve, and a crank on the other end of said rocker shaft and connected to move with the slide block of the governor for the purposes specified.
